In the museum the exhibit of main interest to scholars of "Rediscovery" is the one on Joseph Black, the 18th century chemist who first characterized "fixed air" (carbon dioxide) and who first distinguished calcium and magnesium (1755). He therefore is sometimes credited with the "discovery" of magnesium. His portrait is at the upper left. The exhibit contains utensils and glassware he used in his laboratory.
